Small steel balls fall from rest through the opening at A at the steady rate of two per second. Find the vertical separation h of 3. the two consecutive balls when the lower one has dropped 3 meters. Neglect air resistance. [h = 2.61 m] Hint: Problem can be solved easily by taking A as the reference point and downward direction as positive. Then, x, v, and g will be positive for the falling body.
